[Clinical exploratory application of robotic resection of tumor in segment â §: a report for 7 cases].

Objective: To investigate the feasibility and security of robotic resection of tumor in segment Ⅷ primarily. Methods: The clinicopathologic data of 7 patients who underwent robotic resection of tumor in segment Ⅷ using daVinci robotic system in the Department of Hepato-pancreato-biliary Surgical Oncology, Chinese PLA General Hospital from June 2016 to December 2016 were retrospectively analyzed. The lesion size, the tumor malignance degree mean operation time, intraoperative blood loss and the rate of conversion to laparotomy, postoperative hospital stay, mobidity and motality of all the 7 patients were collected. Results: All the 7 operations were successfully performed with radical resection.The mean tumor diameter was (4.6±1.2)cm. The mean operation time, intraoperative blood loss and postoperative hospital stay were(120.7±21.7)min, (100±106.7)ml, and(7.3±1.8)days respectively.All the patients were discharged successfully with no severe complications. Conclusions: According to our experiences, as a new operationmodel of minimally invasive surgery, robotic resection of tumor in segment Ⅷ has manyadvantages in laparoscopic like less trauma, less intraoperative bleeding, light postoperative pain, shorter postoperative hospital stay and so on. There are some certain advantages in exposure of Ⅷ segment under robotic surgery system. Robotic surgery system is safe and feasible for tumorresection of segmentⅧ, andhas clinical promoting value and application prospect.
